DESCRIPTION:Dayung Koh\, JPL\n\n\nTitle: Symplectic geometry and astrodynam
 ics - the story behind the research collaboration\n\n\nAbstract: I am goin
 g to talk about how the collaboration started and how it has contributed t
 o both mathematic and engineering communities enabling a better understand
 ing of the effect of the dynamics under the influence of three bodies\, es
 pecially the Jupiter-Europa system.\n\n\nStudying astrodynamics is commonl
 y approximated by classical mechanics and solved using differential calcul
 us by engineers. The three-body problem is one of the key topics in astrod
 ynamics\, and it has been studied for decades. The brute-force differentia
 l equation solving approach has been predominantly used. However\, enginee
 rs often confront several fundamental questions: are the two different sol
 utions from the numerical computation qualitatively ‘different’? how a
 re the solutions evolved? If there is a bifurcation\, did the computation 
 algorithm find all the bifurcation branches? If these questions can be ans
 wered\, one solution can tell much about the dynamics of the orbit family\
 , and engineers can confidently build the trajectory catalogue for any des
 ign requirement. Moreover\, we will be able to understand dynamics around 
 celestial bodies which is the primary goal of the study. Interestingly\, t
 here are close links between symplectic geometry and astrodynamics\, shari
 ng the same questions of the three-body problem. A few collaborators from 
 the two fields including Agustin Moreno\, Urs Frauenfelder\, Cengiz Aydin\
 , Otto van Koert\, and Dayung Koh have started an interdisciplinary study 
 complementing each other’s fields. As a result\, the new symplectic geom
 etry tools are successfully applied to trajectory searching in mission des
 ign and bifurcation study in the three-body problem.
